RIOT-ESP8622

Hi,

I’m wondering if RIOT can be used in combination with the ESP8622.

Thank you for considering my request

Best regards

Hi Roger,

RIOT can certainly be ported to the ESP8622, and it would make for a very interesting platform. I think some people (including myself) have briefly looked into this, but there has been created no countable output, yet. The main problem I have encountered so far is their custom CPU core. I have only found part of the information needed (ISA, stack handling, peripheral register descriptions) that is needed to port RIOT, but I have not looked very good for it…

Cheers, Hauke

Hi,

if someone (here in Berlin) wants to try their porting skills I could offer hardware:

- ESP-12E (http://www.ebay.com/itm/171907430053) - ESP-201 (http://www.ebay.com/itm/181846574978)

Cheers, René

Hey,

You mean ESP8266 (Tensilica L106) right?

I would concentrate my power to the upcomming ESP32 (DC L108) with BLE and 416 kb RAM. https://www.sparkfun.com/news/2017

The esp32 has 2 core inside, and seems that RiOT don’t support more than one core?

I was under the impression that the core which the esp8266 is based on isn’t actually custom but is rather a Xtensa CPU by Tensilica which is now part of Cadence.

While Xtensa CPUs may not be as familiar as ARM or MIPS I believe that there’s a reasonable amount of NDA unencumbered documentation available on it floating around the web and in various academic journals.
